Dex EntryOnly skilled Trainers can train Stundev because of their strong electrical power and their recklessness. Stundev hunt by laying underneath sand and then releasing electricity through its horns and spines all over its body into its unsuspecting prey.

"Stundev are lethargic, and spend the majority of their time laying on stones and basking in the sun. Despite this, Stundev are mighty Pokemon, known to give of so much excess electrical energy that they can vaporize nearby water sources. Now if only their trainers could get them to stop napping..."

"Though no longer as able to freely adapt themselves as Tadapt, some Stundev/Finzard/Amphyro/Riplade maintain a limited ability to alter their cells to be more resilient to attacks when they are threatened."

Stundev evolve from Tadapt when exposed to a Thunder Stone. Stundev surround their nests with scraps of metal in hopes of attracting electrical currents. Their homes are infamous for constantly getting struck by lightning.
